Job description

When a new software version for our vehicle controller is released, it will be extensively tested. One of the important tests is an automated test to check if all CAN communication works flawlessly. If not, this generates an HTML error log file of about 5-20 MB, that we had to go through manually, taking roughly 1-3 days. To quicken that process, we have created a Python tool that automatically creates a human readable summary, which saves us a couple of days of tedious work.

We want to have a similar tool for Vehicle Fault Manager (VFM) reports. VFM is a tool that receives all error messages from the truck and tells the digital display what errors should be shown to the driver. A complete VFM test (that takes 5-8 hours) also generates huge HTML files, in the order of 20-30 MB. While the problem is similar, the tool needs to work in a completely different way.
This task includes:

• Understanding the structure of these error reports and how the manual process of extracting human readable data works
• Proposing a format for the human readable output data
• Working together with testing department to influence the format of the HTML input data
• Creating a design for the VFM Parser
• Implementing and unit testing the VFM Parser
• Documenting the tool

• Automating the VFM test to run after a release and also runs the VFM parser
• Extending the tool so it can generate a diff between VFM errors in 2 releases
